When the zipper teeth are closed, the peripheral TPU (thermoplastic polyurethane) of the zipper teeth is tightly combined together, the gap of the zipper can be well sealed with upper zipper teeth and lower zipper teeth, the thickness of the TPU layer of the zipper tooth is larger than that of the TPU layer of the zipper belt, and a convex edge is formed by adapting the TPU to coat and by the integral design. The utility model has the advantages of durability, low cost, water and air resistance, ultraviolet ray resistance, corrosion prevention, ageing and abrasion resistance, and the like.

Maintainence

The SZIP Metalroof is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function if they get caught between the teeth chains. If the SZIP Metalproof closure is used to protect life or sensitive material, the sealing function and cleanness of the chain area should be double checked prior to every usage.
